I apologize to the OP for going off-topic.
Thanks. Those would be on the small side(at least the bore diameter)? Some measurements I just found start with a cylinder bore diameter of .409"
I found these figures for diameter and choke constriction, starting with a cylinder bore diameter of .41", which is what I would have expected, but they also show tighter choked I.D.:
Full Choke, .396, .014
Modified, .405, .005,
Imp. Cyl., .408, .002,
Cylinder, .410, None
Anyway, I'm relieved to know my .375" buckshot will probably be able to get through the muzzle of my old full choke Stevens single shot.
Here are what standard 410 chokes should be.
Full - 0.398"
Modified - 0.402"
Improved cylinder - 0.404"
Cylinder - 0.405"
